You can put this solution on YOUR website! If your sum is 11 and your product is 18 what is the 2 one digit numbers.
-----------------
Equations:
x + y = 11
xy = 18
----
x = 11-y
-----
Substitute for "x" and solve for "y":
(11-y)y = 18
y^2-11y+18 = 0
(y-9)(y-2) = 0
y = 9 or y = 2
---
If y = 9, x = 2
If y = 2, y = 9
=======================
